Kuhn's competition is geared toward raising awareness for prostate cancer. With the NFL already sporting pink gear during Breast Cancer Awareness Month, it's uplifting to see an individual player take on a cause he believes in without the support of the entire league.

There's a Facebook page called "Green & Gold Growing" to help document Kuhn's progress and spread the word about his cause.
